The JBX88263 12-meter ST/ST duplex singlemode fiber patch cable represents premium optical connectivity for mission-critical network environments. Engineered with precision to meet enterprise-grade standards, this cable delivers uncompromising performance for fiber-optic signal transmission across demanding applications. **Key Technical Specifications:** This singlemode fiber patch cable features a 9/125 core construction with G.657.A1 glass fiber, the ideal choice for long-distance, high-bandwidth telecommunications. The ST/UPC connector terminations provide secure, repeatable connections with ≥20dB return loss, minimizing signal reflection and data loss. With insertion loss rated at ≤0.35dB across both 1310nm and 1550nm wavelengths, this cable ensures minimal signal degradation over distance. **Performance & Compliance:** Tested according to ANSI/TIA/EIA-455-171-A standards, the JBX88263 meets the stringent requirements of modern data centers and telecommunications infrastructure. TAA compliance ensures it meets government procurement standards, while RoHS/ELV certification confirms environmental responsibility. The duplex Type A to B crossover configuration is the industry standard, enabling seamless integration with existing network architectures. **Design & Durability:** The riser-rated (OFNR) jacket provides fire safety suitable for vertical cable runs in building infrastructure while the 1.8mm outer diameter ensures easy routing through tight cable management systems. Available in custom lengths beyond the standard 12-meter specification, this cable adapts to unique installation requirements. **Applications:** Ideal for data center interconnects, telecommunications facilities, fiber-to-the-premises (FTTP) installations, and enterprise backbone networks. The singlemode configuration supports long-distance transmission essential for campus networks and carrier-grade applications. **Warranty & Support:** Backed by a 90-day limited warranty and shipped free on orders over $99 from multiple U.S. locations for fast delivery. Ships from Danville CA, Fort Worth TX, or Beaufort SC facilities.
